Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a high-efficiency punching and forming mold for lithium battery cap connecting pieces. Background Technology

[0002] With the increasing maturity of lithium-ion battery technology, lithium-ion batteries are widely used as power batteries in the field of electric vehicles. In recent years, the demand for electric vehicles has been increasing, which has led to higher demands for battery production efficiency. Battery processing requires punching the battery cap connecting piece. However, existing punching and forming dies cannot remove and replace the punched workpiece during the punching process. The machine needs to be stopped from time to time to remove and replace the workpiece. Therefore, the processing efficiency of the battery cap connecting piece is slow and the use is inconvenient. Utility Model Content

[0003] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology, and to propose a high-efficiency punching and forming mold for lithium battery cap connecting pieces.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A high-efficiency punching and forming mold for lithium battery cap connecting pieces includes a mounting plate. A support frame is fixed to the right side of the upper surface of the mounting plate. A hydraulic cylinder is vertically fixed to the top left side of the support frame. An upper template is fixed to the bottom of the push rod at the output end of the hydraulic cylinder. A support base is fixed to the middle of the upper surface of the mounting plate. A collection box is embedded in the lower part of the support base. A stepper motor is fixed to the left side of the upper surface of the support base. A gear disk is fixed to the bottom of the drive shaft at the power output end of the stepper motor. A stamping plate is embedded in the upper part of the support base. A connecting ring is fixed to the outer wall of the stamping plate. A collection tube is fixed to the top of the stamping plate. A lower template is fixed to the upper right side of the inside of the support base.

[0006] Preferably, the stamping plate has eight punching slits arranged in a circular, equidistant vertical pattern on its inner and outer sides, and the cross-sectional area of ​​the punching slits is the same as that of the upper template.

[0007] Preferably, the middle part of the upper template, the middle part of the lower template, and the middle part of the rightmost punching opening of the stamping plate are all on the same vertical horizontal plane.

[0008] Preferably, each of the eight punching openings has a hollow channel inside, and the hollow channel is connected to the lower part of the collecting tube.

[0009] Preferably, the teeth on the outer wall of the gear disk mesh with the teeth on the outer wall of the connecting ring, and the stamping disk rotates 45° counterclockwise in the support seat each time.

[0010] Preferably, the upper left opening inside the support base is provided with a discharge port, and the middle part of the discharge port and the middle part of the leftmost punching opening of the stamping plate are both on the same vertical horizontal plane.

[0011] When the connecting piece to be processed is placed in the punching opening at the front end of the stamping plate, the stepper motor drives the stamping plate to rotate 45° counterclockwise each time through the gear plate and connecting ring. When the front punching opening moves to the far right of the stamping plate as it rotates, the connecting piece in the punching opening is exactly between the upper and lower templates. At this time, the hydraulic cylinder pushes the upper template down to punch the connecting piece. After punching, the hydraulic cylinder pulls the upper template back to its original position, and the stepper motor continues to drive the stamping plate to rotate, so that the front punching opening moves to the far left of the stamping plate as it rotates. The punched connecting piece in the punching opening will automatically pass through the discharge port and fall into the collection box for storage due to gravity. This achieves rapid punching of the connecting piece. The device can continuously punch the connecting piece without stopping the machine, resulting in high working efficiency and greater ease of use. Attached Figure Description

[0016] Legend:

[0017] Mounting plate 1, support frame 101, hydraulic cylinder 102, upper template 103, support base 2, collection box 201, stepper motor 202, gear disk 203, stamping plate 204, connecting ring 205, collection pipe 206, lower template 207. Detailed Implementation

[0018] Example 1, referring to Figure 1-4A high-efficiency punching and forming mold for lithium battery cap connecting pieces includes a mounting plate 1. The mounting plate 1 has a support frame 101 fixed to the right side of its upper surface, a hydraulic cylinder 102 vertically fixed to the top left side of the support frame 101, an upper template 103 fixed to the bottom of the push rod at the output end of the hydraulic cylinder 102, a support seat 2 fixed to the middle of the upper surface of the mounting plate 1, a collection box 201 embedded in the lower part of the support seat 2, a stepper motor 202 fixed to the left side of the upper surface of the support seat 2, a gear disk 203 fixed to the bottom of the drive shaft at the power output end of the stepper motor 202, a stamping plate 204 embedded in the upper part of the support seat 2, a connecting ring 205 fixed to the outer wall of the stamping plate 204, a collection tube 206 fixed to the top of the stamping plate 204, and a lower template 207 fixed to the upper right side of the inside of the support seat 2.

[0019] The stamping plate 204 has eight punching slits with equidistant vertical openings in a circular shape on the inner and outer sides. The cross-sectional area of ​​the punching slits is the same as that of the upper template 103.

[0020] The middle part of the upper template 103, the middle part of the lower template 207, and the middle part of the rightmost punching opening of the stamping plate 204 are all on the same vertical horizontal plane;

[0021] Each time the stepper motor 202 drives the stamping plate 204 to rotate 45° counterclockwise through the gear disk 203 and the connecting ring 205, a punching hole in the stamping plate 204 will be located at the bottom of the lower template 207, waiting to punch the lower template 207.

[0022] The teeth on the outer wall of the gear disk 203 mesh with the teeth on the outer wall of the connecting ring 205, and the stamping disk 204 rotates 45° counterclockwise in the support seat 2 each time.

[0023] When the connecting piece to be processed is placed in the punching opening at the front end of the stamping plate 204, the stepper motor 202 drives the stamping plate 204 to rotate 45° counterclockwise each time through the gear plate 203 and the connecting ring 205. When the punching opening at the front end comes to the right side of the stamping plate 204 as the stamping plate 204 rotates, the connecting piece in the punching opening is exactly between the upper template 103 and the lower template 207. At this time, the hydraulic cylinder 102 pushes the lower template 103 to punch the connecting piece. After punching is completed, the hydraulic cylinder 102 pulls the upper template 103 back to its original position. The punching efficiency is high and the use is more convenient.

[0024] Example 2 differs from Example 1 in that, in this example, all eight punching holes have hollow channels inside, and the hollow channels are all connected to the lower part of the inside of the collecting pipe 206.

[0025] During the punching process, when the air intake pipe of the external vacuum cleaner is connected to the collection pipe 206, the debris generated during the punching process will be sucked away along the hollow channel and the collection pipe 206, thus preventing debris from being present in the punching opening of the stamping plate 204.

[0026] The upper left opening inside the support base 2 is provided with a discharge port. The middle of the discharge port and the middle of the leftmost punching opening of the stamping plate 204 are both on the same vertical horizontal plane.

[0027] As the stepper motor 202 drives the stamping plate 204 to rotate, the foremost punching opening moves to the leftmost side of the stamping plate 204 as the stamping plate 204 rotates. The connecting pieces that have been punched in the punching opening will automatically pass through the discharge port and fall into the collection box 201 for storage due to gravity, thus realizing the rapid collection of the punched connecting pieces.

[0028] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
